CARBURETER.

Specification of Letters Patent.

- Patenefi nprn as, .1908.

Toall whom 'it may concern:

Be it known that I, WILLIAM L. lVAY- RYNEN, a citizen of the United States, and a resident of Dolph, in the county of Hamlin and State of'South Dakota, have invented a new and Improved Carbureter, of which the tion. l

'Ilhis invention relates to certain improvements in carbureters for formmgthe explos1ve charge for mternal combustion englnes,

followingis a full, clear, and exact descripand relates vmore particularly to means.

whereby 4a mixture of uniform composition may be formed irrespective of the uantity of asolenegor other fuel inthe su ply tank, an irrespective of the speed of t e engine. In my improved carbureter the presence of impurities in the liquid fuel does not'interfere with the operation of the device,'as no needle valve or fine passage is employed..

The invention consists in certain features of construction and combinations of parts, all of which will be fully set forth hereinafter and particularly pointed out in the claimt. Reference is to be had to the accompanying drawing, forming a part of this specificaltion, in which the figure shows a section through a carbureter constructed in accordance with my invention.

1n the specific form'of the carbureter illustrated 1n the accompanying drawings, I provide an air supply conduit 10, preferably extending in a vertical direction and having an elbow by which it unites with a horizontally-disposed portion 11 provided with a flange 12 by which the conduit may be rigidly connected to the engine adjacent the inlet valve thereof. Supported adjacent the elbow of the conduit and upon substantially the same level, I provide ali uid fuel container 13 having a supply' con uit 14- at the lower portion thereofand an overllow conduit 15 leading from adjacent the upper portion. Within the container and adjacent the lower portion, I provide a baille plate 16 directly over the inlet end of the supply pipe 14, whereby the incoming liquid is prevented from agitating the liquid in the container to any material extent, thus facilitating th'e maintenance of a substantially constant liquid level even with the overilow pipe 15.-

Within the air supply conduit 10 and adjacent the elbow thereof, I provide a small shallow cup 12 having a conduit operatively connectin it to the container 13 and adapted to .expose 'quid fuel to the action of the air and maintain4 a liquid leveleven with the liquid level inthe container 13.

Thecu`17A is provided with a conduit-18 leading om f 'the' bottom throughthe wall of the air supply conduit 10 and enterin the wall of the con-I tainer 13 below the leve of the overflow pipe- 15. Intermediate the ends of the conduit -I provide a valve casing 19 having a suitable valve 20 for controlling the supply of liquid fuel from' the container to the cup, and any suitablemechanism .may be provided'for o erating .the valve, as, for instance, a

t eaded valve stem 21 extending through a.

packing box 22. The container is closed at the upper end by a suitable cap 23and this j ca is preferably provided witha small air ho e 24 to maintain-the level inthe .container y 13 under atmos heric pressure.

.Within the e bow of the air-pipe 10, and

extending from the upper portion thereof'to a point above the center of the'cup 17, 4I preferably provide a baffle plate 25 serving l to deflect the upper current of air against the surface of the hquid in the cup.

Inthe operation pfmy improved chargeforming means', Athe. liquid fuel is supplied through the conduit f4 at the desired rate'of speed by means of any suitable form of pump, and any excess of liquid overflows through the conduit 15 and returns to the general supply tank. The. 1iqui'd,le velwith"A in the container 13 is maintained constant, as is also'A the liquid level inthe cup 1'7 .which isin open communication therewith. Air is either sucked through the 'conduit 10 byl the engine piston, or may be forced throughby a the li uidfuel and causes a rapidvaporizasuitable blower. .The air in striking the baf- Y fle plate 25 is deflected. against .thesurface of`4 sive charge, which. latter passes outward i through the horizontal portion 11 of the con-- duit 10 and enters the en ine.

Having thus describe vmy `invention, I

'claimas new and desire to secure by Letters Patent:

1. A carbureter, comprising a' li uidfuel.

cup, means for maintaining a liqui therein at a 'substantially constant level, means'for delivering air ,into engagement with. the under surface of said cup, and means fordelos fleeting theair into engagement with the sur- A wl; i i v y v face of the liquid, whereby theliquid is -passing thljough the' conduit is'v deflected brought to the temperature of the airby oonr against the liquidj in the Cup, and means for -duction and evaporated by direct oontaot. maintaining a constant 1i uid 1e've1.
